Curators: Nick Evans (University of Southampton) and Biagio Lucini (University of Swansea) Asymptotically free, non-abelian gauge theories with fermionic matter underly our understanding of quantum theories of force. The strong nuclear force is described by an SU(3) gauge theory; the weak nuclear force by an SU(2) gauge theory. The catagorisation of these theories is likely to be important for understanding physics beyond the Standard Model but is in anycase an interesting field theoretic problem in itself. There are potentially theories which behave rather differently than QCD and understanding these theories will help test our understanding of QCD. Here we provide links that overview the state of knowledge in the field.
